Math CAMPPP 2012

Breakout Session 2Kindergarten to Grade 4

Learning GoalsParticipants will:• Gain an understanding of the various representations for

one half• Recognize and analyze various representations of one

half and some of the common misconceptions• Gain an understanding of the complexity of working with

set models in fractions• Gain an awareness of the existence of fractional

concepts in other areas of the mathematics curriculum

Minds On! Gap Closing Diagnostic

• Which representations of one half would students clearly understand?

• Which representations of one half would likely be confusing for students?

• What misunderstandings may arise?

Action! Solve this problem in several ways

Looking at Student Work• What mathematical understanding do we

see in the work?• Do we see any of the misconceptions

Marian mentioned in the work?• What are some of the misconceptions that

were not part of the plenary?• What strategies could be used to help

students better understand the concept of fractions?

More or less than one half?Prove it!

• Joe struck out 7 out of 17 batters• 8 of the 11 apples were rotten• Bill ate 5 out of 9 cookies• 8 of the 15 seeds that were planted

sprouted

Adapted from Marilyn Burns

To the Curriculum!• Pick a grade K – 4• Find fractional concepts

and understandings in a place/strand where it was previously not anticipated

• How do different models link to the curriculum?

Consolidation – Your Choice:Record: • How can I use this

knowledge to enrich students’ understanding and help them make connections?

whether the glass is half full or half empty. There is room for more of the liquid treasure.
